SPECIFICATION orming part of Letters Patent No. 314,481, dated March. 24, 1885.

Application tiled November 12, 1884.

To a/U whom it may concern:

Beit known that I, JAMns C. Ross, a citizen of the United States of America, residing at Joliet, in the county of Will and State of Illinois, have invented certain new and useful Improvements in Vire-Barbing Machines,

of which the following is a specification, reference being had therein to the accompanying drawings.

Figure l is a perspective view of the machine setup ready for use. Fig. 21s aside view of the barb cutting and forming shear-punches, looking at them on the side on which they are approached by the barb-strip. Fig. 3 is atop plan view of the shear-dies between which the barbing-strip is conducted to the shearpunches, and also shows the manner in which the barbing-strip enters between the strandwires before it is sheared and formed into a barb. Fig. 4 is aperspective view of the headblock, which, in conjunction with the upper shear-punch, furnishes means for forming the two rear prods of the barb, and also shows the strand-wire guides adapted to be replaced by new ones when worn. Fig. 5 is a cross-sectional view of the two strand-wires in front of the barb after it has been cut, formed, and placed in between the strand-wires. Fig. 6 is a side View of the pair of cone-pulleys connected by a belt, the shaft of the upper one having a crank formed thereon to drive a pitman to operate the feed and the two parallel punches. Fig. 7 is a face view of the shearpunches, showing them apart and ready to ad- Vance toward each other to close on the barbstrip to cut and form a barb. Fig. 8 is a similar view of said shear-punches closed upon the barb-strip and having cut and formed a barb. Fig. 9 is a cross-sectional view on line 4 of Fig. 7, looking down, showing a crosssection of the two cutting portions of the upper punch and the upper end of the lower punch; and Fig. l0, a perspective View of a iinished barb as it appears between the strandwires at the instant of its formation.

This invention relates to certain improvements in a machine for automatically cutting or shearing, forming, and seating between a pair of cabled strand-wires a four-pointed flat (No model.)

metal barb cut from a iiat metal barbing-strip after the strip has been fed in between the strand-wires far enough to form a barb. The strand-wires are pulled across the machine between a pair of cutting and forming punches, and at right angles with the length of the barbing-strip, by means of a spooler in a twister-yoke, (not necessary to be shown,) in such .manner that the barbing-stri p may enter between the strands.

Referring tothe drawings, Fig. 1 shows a general view of the machine as it appears when ready for operation, with the exception of a spooler and twister to take the barbed wire out of the machine, which parts are not necessary to be illustrated or described, as they form no part of this invention, and a great variety of devices may be used for said purposes. f

'Ihe principal part of this invention relates to that portion ot' the machine that cuts and forms the barb and seats it in between the two strand-wires.

Heretoforc the usual practice has been to cut and form the barbs by a separate machine, and then set them in between the strand-wires by hand, by which process the barbs cannot `l be set at any regular distance apart or with safety to the operator.

v The means shown for operating the barb cutting and forming parts may be varied in many ways; but the means shown will accomplish the purpose well enough to make the machine successful.

In the drawings, A represents the bed of the machine, which supports the working parts. To the standard I are pivoted a pair of arms, B B', to the outer end of which are respectively secured the cutting and forming punches C C'. A pair of posts, P and P', are arranged, one on either side of the arms BB', near their outer ends, which posts form a guideway to properly guide the arms B B, so that the shear-punches C C will be held in workingposition between them. The two arms B B are operated to move the shear-punches C Gto and from each other by means of the working-beam D, pivoted at its center to stud-post P3. Each end of said working-beam has pivoted to its side a slide (shown at H H') to slide in the rectangular boxes G G' on the inner edges of said arms. Said working-beam DL is caused to oscillate by means of the pitman R, pivoted at one end to said working-beam and attached at its opposite end to the crank R'of cone-pulley L. (Shown in Figs. l and 6.) A belt, e, connects cone-pulleys L L', and by shifting the belt e on said cone-pulleys greater or less speed can be given to the operating parts of the machine. lates, it reciprocates the cutting-punches C C' on the outer ends of arms B B to and from each other to cut and form a barb. The iiat metal barbing-strip E is fed into the machine between the rollers S S' and between the dies D D', to emerge from between their cutting ends, and enters between the two strand-wires W, as` shown in Figs. l, 3, and 7. This barbstrip is fed in intermittently far enough each time to form a barb by means of a dog-feed (shown at F, Fig. l) operated by pitman R through the medium of lever F2. This lever F2 is pivoted at f and integral with crank F', to which dog F is attached, and when said crank is oscillated it feeds forward the barbstrip E far `enough each time for a barb, as shown in Fig. 3. The rollers S S may be rotated intermittently to feed forward the barbstrip, if desired, and thusdispense with dog F.

At one side of the machine, and next to the shear-punches C C', is attached ablock, O, v(shown in Fig. land in perspective in Fig. 4,) having strand-wire guides d and d', which are detachably connected thereto, to be replaced by new ones when worn. The strand-wires pass through these guides through the holes v2 and o3, respectively, from the side ofthe machine opposite io that shown in Fig. l, between the two shear-punches C C', and far enough apart so that the barbstrip is fed in between them, as shown in Figs. l, 3, and 7. The said shearpunches are provided with the grooves or recesses Z and Z', respectively, for the reception of the strand-wires when the punches close together to prevent their severing the strandwires. When the barb-strip E has been fed in far enough to emerge from between the dies D and D' far enough to make a barb, and between the two strand-wires in the position shown in Figs. 3 and 7, the shear-punches move toward each other until they close upon the barb, as shown in Fig. 8. When they so close, the shear-point a, in conjunction with die D, shears the prod m of the barb and carries it downward on the former-bed 'u of block O and bends itin the form shown in Figs. 5 and 10. Shear-pointa'in likemanner, in conjunction with die D', shears the prod m' of the barb, and carries it upward against the inclined face of'punch Gand bends it in the form shown in Figs. 5 and 10, so the two points are spread apart, as shown in said figure, and the barb severed entirely loose from the barb-strip. When the two punches so close on the barb to cut and form the prods m and m', as stated,

When working-beam D4 oscilf their shear-points a2 and a slit the opposite pointed end of the barb to form the other two prods, m2 and m3. Shear-point a carries prod ma upward against the inclined face of punch C and bends it in the form shown in Figs. 5 and l0, and shear-point a? carries prod m2 downward on the former-bed n', Fig. 4, and bends it in the form shown in Figs. 5and l0, so that by one movement of said shear-punches, as stated, a complete four-pointed ilat metal barb is formed and set between the two strand-wires in the form shown in Fig. 5. As soon as a barb is thus formed and set between the two strandwires, the two strand-wires, by means of their frictional contact with the barb,on account of their being continually twisting together toward and on the barb, carry the finished barb, after it has been released from the shearpunches, along out of the way of the next succeeding barb. The strand-wires travel continuously through the machine, and are thus supplied with barbs as they travel and as they are being twisted together. Their twisting together at the time and after the barb is thus applied causes them to grasp the barband prevent it from falling out. The distance the barbs are to be placed apart depends upon the velocity or speed at which lthe shear punches are driven. Their speed is regulated by means of the cone-pulleys L and L' and belt e. By moving the belt from one side to the other the speed of the shear-punches may be either increased or diminished, and thus set the barbs nearer or farther apart. The 'dog shown in Fig. l at S4 is for the purpose of preventing the backward movement of the barb strip when dog Fis moving back for a new grip. Dog S4 is hinged at its upper end between the standards S2 S2, which also support the rollers S S'. The distance the barb-strip is fed in at each feed is regulated by means of the arm F2. The upper end of said arm passes up between the pitman R and a strap on its side. (Shown IOO by the dotted lines in Fig. 1.) The length of 1ro said strap determines the stroke of said arm. The finished product of the machineis shown in Figs. 5 and 10.

Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is as follows, to wit:
